MOTOR-CYCLE.

Specification of Letters Patent. Patented A 11 1916 Application filed February 19, 1912. Serial No. 678,472.

1 To all whom it may concern:

Be it known that 1, ROBERT L. BAILEY,

a citizen of the United States, residing at Portland, in the county of Multnomah and State of Oregon, have invented a new and useful Improvement in Motor-Cycles, of which the following is a specification.

This invention relates to motor cycles, and has for its primary object to provide a construction of the same whereby shock and vibration during riding will be greatly reduced in such a manner as to render riding as easy as possible.

A particular object of the invention is to provide a construction of the front part of the machine whereby the front wheel is so mounted with respect to the front fork and front portion of the main frame, that all shock and vibration will be absorbed.

A further and important object of the invention is to so mount the engines that the vibration due to the propulsion of the same will be equalized and to this end the invention consists in providing horizontally 0pposed engines disposed symmetrically to the angle of the main frame, at which point the crank casing of the engines is mounted.

For a fullrunderstan ding of the present invention, reference'is to be had to the following description and to the accompanying drawings, in which l I Figure 1' is a side elevation of a motor cycle showing the features of the present invention in their proper relation. Fig. 2 is a side elevation of a motor cycle-looking from the side opposite that shown in Fig. 1.

Throughout the following detail description and on the several figures of the draw ings, similar parts are referred to by like reference characters.

Referring to the drawings, 1 represents the main frame of the machine, the same being of ordinary construction and its partic'ular structure forming no part of the present invention.

2 represents the handle bars and 3 are the handles,,b,oth of ordinary construction. A flat leaf spring 4, of thevstructure particularlys'hown in the drawings, having a front portion which turns under the main portion of the spring, is connected to a'plate, whlch latteris' attached to the main frame of the machine, and fastened thereto by any suitable means. A pair'of false forks 5 are connected to the'in'ner end of the intur'nedportion of the flat leaf spring 4 and extend substantially vertically downwardly therefrom one false fork being disposed on each side of the front wheel of the machine. The axle of the front wheel is denoted by .7, and to said .aXle a pair of rocker arms 6 are pivotallyconnected, one on each side of the wheel.

The lower ends of the false forks 5 are connected to the rocker arms at points intermediatethe connection of the rocker arms with the axle and the upper ends of the same. A connection is thus established between the flat leaf spring 4 and the axle of the front wheel, through the rocker arms 6 as intermediate members. The upper endstion described, consisting of the connections of the axle, rocker arms, false forks, the

front fork and the flat leafspring, all shock and vibration due to rough riding will be absorbed, thus rendering the riding easy and pleasant. The front wheel, is denoted by 9; 1 0 is the tire of the front wheel and 11 is the mud guard therefor, the latter-being of ordinary construction but is connected to the rocker arms by means of the rods 11, one of which is arranged on each side of the front wheel and which serve as braces for the mud guard and tend to reduce and equalize vibration. Y J t 7 "A rod 1 connects thetwo downwardly extending portions 1 and 1 of the main frame 1,the rod 1' being disposedin a substantially horizontal direction, as. is clearly shown. Resting on the rod 1 and between the latter and the outer portion of the main frame, the gasolene tank 18 is disposed, the same being provided with a filling cap 12 which is also;providedwith a stop or shutoff valve'13 but whichforms no part of the present invention. Disposed adjacent to the gasolene tank 18 and between therod 1? and the upper part of the frame 1 is a lubrieating, oil .tankol'? having'afiller cap 15 analogous to that formed on the gasolene tank and a small pump 1% is provided for the purpose of forcing the lubricating oil down to the crank casing.

19 represents a small pipe substantially vertically disposed which leads the gasolene from the tank to the carbureter, and the downwardly extending tube 20 conducts the lubricating oil from the oil tank to the crank casing, which latter is denoted at 27.

Thesaddle of the machine isshown at 16, the same having the front spring 16 and the rear springs 16.

The carbureter of the machine is represented at 21, the same being of ordinary construction, and is disposed between the down-' wardly extending portions 1 and 1 of the main frame, it being mounted adjacent to the crank casing 27, as shown. A control Wire 22 connects the carbureter 21 with the. handle bars and is provided for the purpose of regulating the feed of the gasolene to the carbureter, and to also control the mixture of the product which passes through the carbureter.

23 represents the manifold and after the proper mixture is produced in the carbureter, the same is discharged into the manifold, by means of which it is conveyed directly to the engine cylinders.

. It is to be noted that the arms of manifold 23 are laced through the frame, one arm extending at one side of portion 1 and the other arm at the other side of portion 1 of the frame, so that the carbureter is sus tained in the most accessible position possible while, by being in the line of the frame, it is free from danger of injury from contact of the legs or feet of the operator. This arrangement of the manifold also provides a simpl and efiicient means of accommodating the disposition of one cylinder at one side or the other while horizontally 'alined.

24 is a magneto of ordinary construction and 25 is a control wire leading from the magneto through the frame of the machine to the handle. bars, by which the magneto may be controlled in the ordinary manner. The construction and connections of the wires 22 and 25 form, however, no part of the present invention and need not be further described.

26 represents the magneto gear casing in which a chain of gears is housed, this being for the purpose of properly timing the explosions which take place in the engine cylinders. V

I The crank casing 27 hereinbefore referred to is disposed at the angle produced by the connection of the downwardly extending portions 1 and 1 of the main frame in such a manner that the crank axle therein will be disposed exactly at the connection of said members.

The manifolds 23 are provided with th By the arrangement just described of the i two opposed engine cylinders lying in a substantially horizontal plane which includes th crank axle, and by the provision of arranging the crank casing and crank axle at the angle produced by the two downwardly extending portions 1 and i of the main frame, the vibration due to the propulsion of the engines is equalized. Thus no shocks or vibration can be transmitted to either the front portion or the rear portion of the machine, as the same is taken up and equalized at the angular connection of the downwardly extending portions of the main frame. This feature constitutes a great ad vantage toward making the riding of the machine easy, thevibration transmitted from the engines to the front and rear wheels having been heretofore a decided disadvantage.

The engines are provided with exhaust valve stems 31; 32 is the casing for the cam gearing for the valve stems; and '33 is the exhaust manifold which leads directly to the muffler 34, the latter being disposed below the rear cylinder 30.

The pedals of the machine are denoted by 35.

86 is a pedal control rod for operating the brake band, the particular structure and connections thereof not being fully illustrated herein, while 37 is a rod or bar leading from the pedals to the clutch of the rear wheel.

38 is the axle of the rear wheel; 39 is the brake drum therefor and 40 is housing for the gears by which'the rear wheel is propelled. The housing 40 also contains the clutch members of the rear wheel, but the same are not shown in the present case.

41 represents the rear fork terminal, the

object of which is to connect the frame members which terminate near the rear axle with the centrally disposed mechanism of the ma- The means for automatically shifting the gears so as to obtain a change of transmission to and from high and lOW speeds and neutral, is particularly described in-a copending application and may here be briefly referred to and consists of the lever 47 pivoted to the main frame 1, the lever being movable over a sector plate 4:7 Which is provided With a plurality of openings in Which a pin 47 on the lever may engage. The lever is connected With a rod 46* Which latter is connected With the energy storing device 46 consisting of a barrel in which springs are disposed in such a manner that When the rod 46 connected to the lower portion of the energy storing device 46 and Working therein, is held in a fixed position, the springs Within the casing 46 Will be compressed and the energy stored up by such compression may be used when the rod 46 is released. The latter is connected With the bell crank lever 45 pivoted to the transmission casing and connected at one end to a rod 45 which enters the transmission casing and eflects the shifting of the gears so as to produce the change of transmission. Movement of the rod 45* is controlled from the Copies of this patent may be obtained forfive cents each, by addressing pedals through the instrumentality of the lever device 48 Which, however, need not be described herein.

Having thus described the invention, What is claimed as new is: V

In a motor cycle, the combination, With a frame, of an internal combustion engine sustained 'at the loWer portion of the frame and comprising a plurality of cylinders, a carbureter disposed in the line of members of the frame, and a manifold for delivering gas to the cylinders interlaced through the members of the frame With one arm of the manifold extending from the carbureter at one side of one of the frame members to one of-the cylinders and the otherarm of the manifold extending past another frame member at the opposite side thereof to the other cylinder.

In testimony that I claim the foregoing as my own I hereunto attach my signature In the presence of THOMAS BILYEW, E. OGARA.
